HTMLB multi-language issue after upgrade

Hi all,

We recently upgraded from EP5 to EP7. The R3 is still on 46c. On our purtal, we have a htmlb textbox that displays the Description of a Material In Local Language. This field was showing properly in EP5. But in EP7 it is showing scrambled characters. I have tried to set the encoding in the frontend to Unicode(UTF-8) and also tried Korean, but still the display is scrambled. How do I get the description field to show the text in the actual language (for eg Korean)?
